RDV: “Unable to Connect”

I have tried to launch the RDV tool from multiple computers and web browsers and have come across the same problem. It says that it was unable to connect and there is a network error where the remote host closed connection during handshake. It gives the options to retry or switch to a signed applet but neither of these options work. Is this a problem on your end or my end? If it’s on my end what can I do to launch the tool through the hub?

Thank you.

    Hi Caroline,

    Are you still experiencing this problem? If so, could you please post a screenshot of the error? I didn’t see much in the code when I grepped for “handshake”. I only saw something about an unrecognized FlexTPS certificate. I need the exact error message. Also, I’d like to know which version of RBNB and RDV you are running. Are you able to ping the server you are trying to connect to? Can you transfer files between the computers?

      Hi Michael, I can now access RDV via the “Launch Tool” app but am unable to access RDV data from a project I have created (#1134 – Virtual Laboratory Modules on Materials and Structures). I am trying to access this data from my laptop but it will not work. I uploaded the RDV setup file to Experimet 1, Trial 2, Rep 1, under unprocessed data. To try to import the data to RDV from my laptop I go to RDV through the “launch tool” app then go to import -> browser -> projects -> NEES-2012-1134.groups -> Experiment 1 -> Trial-2 -> Rep-1 -> Unprocessed_Data -> January 2012 Test.rdv Please let me know of a different approach that will work. Thank you for the help, Caroline Williams

        Sorry for the late response. I just noticed you posted an update. I would need to see a copy of the “January 2012 Test.rdv” file. I haven’t used the feature in RDV to import data locally before. I usually run a Data Turbine server and connect RDV to that. We are kicking around some ideas for automatically transforming NEEShub experiment data into Data Turbine instances. That way, a person could connect an RDV client to any NEEShub experiment.
